SIM 800L Quad-bands 1900 MHz GSM GPRS arduino + Antena

SIM 800L Quad-bands 1900 MHz GSM



Acest modul Nu are 3G deci nu merge RDS-DIGI
Daca vreti GSM cu 3G - RDS - DIGI, vezi (click) la anunturile utilizatorului



ATENTIE!

Conf. datasheet tensiunea maxima de lucru este de 4.2V dar si 5V pe ceilalti pini dar comunicatia Seriala (RX,TX) este pe 3.3V

Daca acest modul se conecteaza la Arduino ... cat si la alte dispozitive ce tensiunea nivelului logic este mai mare de 3.3V mai precis 5V este necesar acest convertor

Am si asa ceva si costa 10 lei

Daca nu se respecta interconectarea corecta privind nivelele de tensiuni logice NU OFER GARANTIE

Un efect de exemplu, daca conectam un modul ce are comunicatie de 3.3V la Arduino UNO ce are nivelul logic de 5V, RX (I2C dupa caz) din modulul de 3.3V se va arde si devine scurt fata de GND !!!

In acest caz modulul devine inutilizabil.
